CLP said electricity supply for about 1,000 customers at Tsuen Wan Centre have been affected due to malfunctioned equipment.
The power firm said electricians were working to fix the issue.
Households in five buildings were affected, with their power and fresh water supplies disrupted, according to Kwai Tsing District Officer Edric Leung.
A resident surnamed Lui said power supply in her unit had been disrupted since noon.
“It was just past 11am. With just a ‘pop’ sound, the power went out. I didn’t come downstairs, but when I opened the door, it was all black, then I realised something had malfunctioned,” she said.
A woman surnamed Wong lived on the sixth floor in one of the buildings.
“I haven’t seen a power cut in such a long time. I feel a bit troubled having to grab my belongings and go elsewhere. Our family has elderly members, so we had to walk down the stairs slowly,” she said.
She said her family would temporarily stay at her sister’s place in Kowloon Bay.
"Investigation revealed that the malfunction occurred in the buildings’ power system and there was no discrepancy in the electrical grid," Leung told reporters in a briefing.
"And because the buildings’ power system malfunctioned, the power supply for the five buildings – including indoor areas, public spaces, and the lifts – were completely cut off.
"A few hours after the incident, we also received reports that the fresh water supply had been suspended."
Leung said officials have launched a cross-district coordination mechanism to handle the incident due to its scale.
He added that five temporary shelters and the Tsuen King Circuit Sports Centre have been opened for affected residents, and care teams have been deployed to help those in need.
